PROCESS AND REACTOR FOR CARRYING OUT AN EXOTHERMIC REACTION

摘要

The present invention relates to a process for carrying out an exothermic reaction in the presence of a solid catalyst in a three-phase slurry reactor (1) comprising a slurry zone (3) and a freeboard zone (5), in which slurry zone (3) the catalyst is kept in suspension in a slurry liquid, and in which freeboard zone (5) a liquid reflux is maintained to remove catalyst from the freeboard zone and, preferably, recycling the catalyst to the slurry zone (3). According to a further aspect, the present invention relates to a three-phase slurry reactor (1) adapted to the process, in particular a three-phase slurry reactor (1) wherein the freeboard zone (5) contains means to trap catalyst particles (10).
